Description
NAG1 Performance TCM Module
Upgraded Transmission Control Module for Dodge, Chrysler & Jeep NAG1 (722.6) 5-Speed Transmission
The N2 Speed NAG1 Performance TCM Module is a pre-programmed transmission control module designed to improve the performance and responsiveness of vehicles equipped with the NAG1 (W5A580 / Mercedes 722.6) 5-speed automatic transmission. This upgraded module features optimized transmission calibrations that deliver quicker shifts, improved torque management, and enhanced overall drivability.
Factory transmission calibrations are designed primarily for comfort and longevity, often resulting in slow or soft shifts and conservative shift scheduling. The N2 Speed performance TCM module replaces the stock module with a performance-optimized calibration engineered to unlock the full potential of the NAG1 transmission.
This upgrade is ideal for vehicles with bolt-on performance modifications, camshaft upgrades, forced induction systems, or increased engine torque where improved transmission response and shift behavior are critical.
Key Performance Features
Faster, More Precise Shifts
Optimized clutch pressure and shift timing tables reduce shift lag and improve acceleration.
Improved Torque Handling
Enhanced torque management calibration allows the transmission to better handle increased horsepower and torque.
Performance Shift Scheduling
Shift points are recalibrated to keep the engine operating within the optimal power band.
Reduced Shift Lag
Improved gear engagement for quicker throttle response and smoother power delivery.
Enhanced Driving Experience
Provides better control during spirited driving, performance street use, or drag racing applications.
Plug-and-Play Upgrade
The NAG1 Performance TCM Module is designed as a direct replacement for the factory transmission control module, allowing for a straightforward installation without complex programming procedures.
Once installed, the module immediately operates with the optimized performance calibration, delivering improved transmission behavior and responsiveness.
